      Can be measured between the incident wavefront and the boundary

    • C. 

      Is equal to the angle of reflection

    • D. 

      Does not depend on the frequency of the source

    A concave mirror has a focal length of 30 cm.  If an object is placed 45 from the vertex of this mirror, the image will be:
    • A. 

      Larger and inverted

    • B. 

      Smaller and inverted

    • C. 

      Larger and upright

    • D. 

      Smaller and upright

    • E. 

      The same size and inverted

  • 8. 
    As an object is placed further and further from a concave mirror:
    • A. 

      The image becomes virtual

    • B. 

      The image will get larger and larger

    • C. 

      Eventually, no image will be formed

    • D. 

      The image approaches the focal point

    • E. 

      The image approaches the centre of curvature

  • 9. 
    When using the mirror equation and the magnification equation for curved mirrors, which of the following is FALSE?
    • A. 

      Convex mirrors have a negative focal length

    • B. 

      If an image is larger than the image, its magnification is >1.0

    • C. 

      The distance of the image in convex mirrors will always have a negative value
